Self-adaptive electrolytes expand electrochemical stability window, eliminating trade-off between fast charging and high energy density

"phase equilibrium looks at overall dynamic real-time electrolytes as system rather than molecules... salting-out effect phase-separation occurring when salt addition to solution (charging process inherently generates electrolyte salt concentration gradients) prompts some components to become less soluble... concentration-driven phase behavior adaptively expands its stability window during operation, based optimizing each electrolytes' 2 solvents + a salt, formulated at cloud point... improved stability, Coulombic efficiencies"
